Okay, so my old computer died. Bought a new refurbused one with Windows 10. Did the online upgrade for the ShopBot software. All went well until I tried to cut a test circle. At first it wouldn't respond to the ZeroZ Axis command. Then I send the router on a little trip, when I told it to "Go Home" it didn't make it very far. So basically I did something wrong during the install. What could it be?
